Answer:
RR x rr / Rr x RR
Explanation:
For all of the first final generation to all produce round peas, it means the parents crossed were pure breeds of both dominant and recessive genotype or one of the the parents is an heterozygote and the other is a pure breed dominant. The resulting peas will have a phenotype which is the observed round shape but their genotype may be either the homozygous RR or the heterozygous Rr.
Answer:
B
Explanation:
Helicase is the enzyme that unwinds the DNA by breaking hydrogen bonds between the two strands. It forms the so called replication fork.
Answer:
The lytic cycle has 6 stages: Attachment, penetration, transcription, synthesis, maturation, and lysis.
Explanation:
- Attachment: is the first step of the lytic cycle, and it consists of the attachment of the virus to the host cell, which is the cell that the virus will infect.
- Penetration: once that the virus is attached to the host cell, this penetrates the cell's membrane to introduce its DNA. When the virus DNA is inside the cell's DNA is destroyed.
- Transcription: now the virus has all the machinery to reproduce itself. In other words, the cell starts the transcription of the virus's DNA.
- Synthesis: the cell synthesizes the virus' DNA and proteins.
- Maturation: in this process, the new virus is assembled and ready to be outside the cell.
- Lysis: as the viruses are ready to infect other cells, they go out of the host cell by lysis, which is a process where the membrane is broken and the cell dies to free what is inside.
It is very rare for people to distinguish which is which, There is currently no way to distinguish, in the absence of independent evidence, whether a particular memory is true or false. Even memories which are detailed and vivid and held with 100 percent conviction can be completely false. *I got this info from a website*
